摘要
设H是Hilbert空间,T=(T_l…T_n)是H上有界线性算子组,本文利用Curto算子定义了T的联合谱概念,并讨论了与之有关的若干问题,特别地,对亚正规算子组情形推广了Arora.S.C.的结果.
Let H be a Hilbert space , T be an n- tuple of bounded linear operators; Using Curto operator , we define the joint spectrum of T and discuss some questions. In-particular , We extend Arora's result for several hyponormal operators.
